WV ATTORNEYS Patented Jan. 11, 1938 UNITED STATES PATENT OFFICE 8 Claims.

The present invention relates to apparatus for staining or similarly treating shingles and the like, and has particular relation to a relatively small and compact machine for dipping shingles into a bath of stain or other liquid and then removing excess liquid from the shingles.

According to my invention, the apparatus includes means for dipping the shingle and means for removing excess stain, contained in a small and compact unit which may be inserted in the barrel in which the stain is delivered or a similar container, so that such barrel serves as the dipping tank. The apparatus is relatively light in weight and may therefore be moved readily from one barrel of stain to another, as when it is desired to use stain of a different color, or the apparatus including the container may be rocked as a unit to agitate and mix the liquid therein. My invention contemplates a device having 90 means for gripping shingles, carrying them down into the bath of stain and then returning them, the gripping means automatically releasing upon the return, and the means preferably being arranged so that one shingle is being carried downwardly as another shingle is returning. Brushes are provided above the bath for removing excess stain from the shingles during the return stroke.

These and other objects and advantages will become apparent from the following description of the typical embodiments of the invention shown in the accompanying drawings, wherein:

Fig. 1 is a perspective view of one form of the apparatus;

Fig. 2 is a view of the device in side elevation with parts broken away on difierent vertical planes to expose the interior construction;

Fig. '7 is an end elevation, partly in vertical section, of the device shown in Fig. 6; and,

Fig. 8 is a perspective view of an element of the device shown in Figs. 6 and 7.

As shown in Fig. 1, the shingle staining unit II is inserted in a barrel or similar container I I2 which may contain stain, and in fact may be the container in which such stain is delivered. The unit II may have side walls I3, end walls I4 and bottom wall I5. The upper ends of the side walls terminate in inwardly directed portions I6, which merge into outwardly extending horizontal walls H, the latter joining upper side walls I8.

Within the frame thus formed are a laterally spaced series of inverted U-shaped rods I9, the vertical legs 2I, of which are spaced inwardly from and are substantially parallel to side walls I3. The bight portion 22 of each rod is in approximately the horizontal plane of walls I1 and merges into legs 2|, by the curved portions 23, that extend toward inwardly deflected portions I6 of the side Walls. The rods have eyes 24, at the lower ends of legs 2I, the-eyes receiving and being supported upon horizontal rods 25, that extend between walls I4. The curved portions 23 at the upper ends of rods I9 engage horizontal rods 26, which likewise extend between walls I4.

Upper and lower shafts 21 and 28 are journalled in bearings 29 and SI, secured to end walls I4. To the shafts are secured upper and lower sprocket wheels 32 and 33 respectively, upon which are carried endless chains 34, each chain 34 being adjacent one end wall I4. Corresponding links 35, 35 of the two chains have ears to which are secured eyes 31 at the ends of horizontal pivot pins 38. Links 36, 36, on the opposite sides of the chains from links 35, 35, likewise have ears to which are fastened eyes 39 that are formed on the ends of pivot pin 4|.

Pivoted to pin 38 is a pair of clamp members 43, and pivoted to pin 4| a pair of similar clamp members 44, the members of each pair being pressed toward each other by a plurality of torsion springs 45. It will be seen that as the shaft 21 is rotated in a clockwise direction (as the device appears in Fig. 3) the left side of the chains, including links 35 and clamp members 43, will move upwardly; and clamp members 44, carried by links 36, downwardly, counterclockwise movement of the shaft will effect an opposite movement of these parts. During both movements, clamp members 43, and 44 are guided and retained substantially upright (although freely pivoted to rods 38 and 4|) in the channels between the side walls I3 and adjacent upright portions 2| of rods I9.

At the upper end of each such channel, and secured to each end wall I4, is a block 46, preferably having a wedge shaped lower portion 41 and parallel upper side walls terminating in shoulders 48, 48 which serve as stops. The blocks are in the paths of the end or finger portions 49 of the clamp members, so that as the latter move to their upper limit positions (wherein portions 49 of the clamp members abut shoulders 48, 48) the fingers 49 will engage and be spread apart by the wedge 41 against the resistance of spring 45. In this opened position of the clamp or shingle grippingmembers the end of a shingle may be inserted by the operator between the clamp members.

Resting upon horizontal walls ll are brush bodies 5|, having inwardly directed bristles 52. Similar brushes 53 but with outwardly directed bristles 54, rest upon the bight portions 22 of rods l9. Each brush body has extending from each end thereof a threaded shank upon which spread or opened by wedge 41.

7 then outwardly directed.

In operation, with the unit II in a container [2 of stain or other liquid with which shingles are to be treated, the shaft 21 may be rotated in-a clockwise direction until clamp members 43 are in their uppermost position and have been For enabling such operation the shaft 21' may have a wheel 58 provided with handle 59. Upon the clamp members 43 being spread or opened a shingle 6| maybe inserted therebetween, the operator moving the shingles'downwardly between opposing brush bristles 52 and 54 until the end of the shingle engages or approaches pin 38. The handle may now'be turned in the opposite or counterclockwise direction, causing the clamp members 43 to move downwardly, during which motion their ends 49 will pass beyond wedges 41 allowing the springs toclose the clamp members, thereby causing the latter to grip the shingle BI and carry it downwardly into the liquidin container l2.

Continuation of this movement will bring clamp members 44 to their upper limit positions wherein they are spread or opened for the reception of another shingle. 'After insertion of 'the latter the handle 59' is again moved in a clockwise direction, lowering clamp members 44 and the shingle carried thereby, and raising clamp members 43 and shingle 6i. During the latter part of this movement the shingle 6| will be moved upwardly between the opposing bristles 52, 54, causing excess liquid to be wiped from the upper end and then from the sides and edges of the shingle and spreading the liquid loosening wing nuts, or they may be removed for cleaning or replacement'by upward move-' ment as permitted by the vertical portions of the slots.

In the arrangement shown in Fig. 5 a motor "62 drives the shaft 21, the motor being geared to a reversing gear 63 having a drivenshaft connected by pulley 54 and belt 65 to thewheel 1 Figs. 6, 'l-andflmayalso be driven by-the powen 5 -58. .t'hereversing' 'gearmay have a conveniently located handle 66 or other suitable manual or automatic control whereby the shaft 21 may be caused to rotate in one and then the other direction or to stop. Slippage of the belt 65, or a slip clutch associated with the reversing gear, may be provided to prevent damage to the machine should the drive continue to operate without immediate reversal after the clamp members have reached a limit position.

In' the embodiment of the invention shown in Figs. 6, 7 and 8, the side walls 1 l have outwardly and thence return bent flanges l2 and 13, and the end walls 14 extend upwardly beyond the a side walls for retaining a metal frame 75 which holds brushes l6 and H. The end walls of frame 15 have horizontal slots 18 which pass threaded fasteners for holding the brushes and enable horizontal adjustment of the brushes, i. e., enable adjustment of brushes l6 and 11 toward or away from each other. The frame 15 has secured thereto bolts which extend through vertical slots 19 in the upper edges of end walls 74, and by loosening wing nuts8| threaded to these bolts the frame 15 and the brushes therein may be removed as a unit.

Parallel to and spaced from side walls H to form guides for shingle gripping members are inner walls 82, the upper ends of which are anchored to angle bars 83. The shingle gripping members comprise a plurality of clamps 84' (Fig. 8) secured to a cross bar 85 carried by an endless chain 86. The latter is supported upon and operated by upper and lower sprocket wheels 81 and 88, respectively, secured to transverse shafts 89 and 9| journalled at their ends in bearings carried by end walls 74. One bar 85 is disposed adjacent each side wall H, and the ment causes the fingers to move outwardlyfrom the spring. 93, opening the clampingjaws against the resistance of springs. 'As'shown in Fig. 6,

'7 and 8 a plurality of gripping membersz84 are held to each bar- 85 by a strap 91 secured tothe bar by fasteners 98. r 7 1 Preferably'disposed above shaft 89 is shaft 99 having'a handle I ill for operating the device, the shafts being connected by a pulley'and belt drive The pulley wheel on shaft 99 is preferably larger 7 7 than that on shaft 89, so that one turniof the handle llll will suifice to raise one bar 85 from its lowermost to its uppermost position. V

I The device operates in substantially the sam manner as the device shown'in' Figs. 51 to 4' inclusive, shingles inserted between jaws 92' when raised being gripped by'action of springs93 as the jaws are'lowered and the fingers 94 leave angle members 95 and 96. The shingles are lowered into the stain or other liquid bath upon continued rotation of the handle and 'upon reverse,

rotation are raised and moved between the bristles of opposing brushes l8 and 11 for removal of excess liquid;

It will be understood that the device shown in drive means similar to those shown in Fig. 5, or by other suitable drive means, instead of by the handle "II.

It will be understood further that the devices shown in Figs. 1 to 4 and 6 to 7, inclusive, may be made small and light enough to permit an operator to rock the unit, including the device and the fluid container in which it is mounted, for the purpose of agitating and mixing the liquid in the container in instances where the same may be desirable. Or, if the container [2 is of the usual round type, as illustrated, I have found that the unit ll may be spun around in the container with the effect of thoroughly mixing the liquid therein.
